In the middle of the screen, there are many small planets, some are close and some are far away. If you are close, you only need to jump one step, and if you are far away, you need to jump two steps. Click on the left side of the screen to jump one step; click on the right side of the screen to jump two steps, if you falls from the planet, the game fails.

Victory: The more planets you skip, the more items you pick up, and the higher your score
Fail: If you don't jump to the planet, the game fails
